The Speer DeepCurl 38 Special 158 grain hollow point ammunition delivers controlled expansion and deep penetration for serious defensive applications. This bonded-core technology prevents jacket separation while maintaining weight retention through barriers.
What Makes This Different
The DeepCurl design bonds the lead core to the copper jacket using Speer's proprietary hot-core process, eliminating the jacket separation common with standard hollow points. This construction maintains 95% weight retention even after passing through heavy clothing, wallboard, and auto glass. The hollow point cavity features a precise taper that initiates expansion at lower velocities while preventing over-expansion at close range.
Key Features
- Bonded-core construction prevents jacket separation for consistent performance
- 158 grain weight provides optimal momentum for deep penetration
- Hollow point design expands reliably at velocities as low as 900 fps
- Compatible with all 38 Special and 357 Magnum firearms
- Nickel-plated cases resist corrosion and ensure smooth feeding
- 100 rounds per box with 5 boxes per case (500 total rounds)
- Manufactured to SAAMI specifications for consistent performance
Law enforcement agencies have adopted this load for its predictable terminal ballistics and barrier penetration capabilities. The 158 grain bullet weight matches traditional police loads while the bonded construction addresses modern defensive requirements. Testing shows consistent 0.65-inch expansion with 14-16 inches of penetration in ballistic gelatin, meeting FBI protocol standards for duty ammunition.
